WATCH-REG U LA'TO R.

SPECIFICATION forming part of Letters Patent No. 414,449, dated November5, 1889.

Application filed June 7, 1889. Serial No. 313,488. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. SoHIM- MEL, of WVallace, in the countyof Shoshone and Territory of Idaho, have invented a new and ImprovedWVatch-Regulator, of which the following is a specification, referencebeing had to the annexed drawings, forming a part thereof, in which-Figure l is a plan View of a portion of a watch-movement, showing theapplication of my improvement. Fig. 2 is a transverse section'taken online so so in Fig. 1, and Fig. 3 is a detail side elevation of thespirally-grooved traveling nut.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to construct a simple and effective devicefor moving the regulators of watches, whereby the regulator may bepositively moved a short distance.

My invention consists in the combination, with the regulator, of acurved screw and a nut arranged to travel upon the screw and providedwith a circumferential groove near one end for receiving the end of theregulatinglever, the said nut being provided with heli cal grooves, andin combination with the helically-grooved nut of a star-wheel pivoted ona stud or screw projecting from the regulator and provided with pins forengaging and turning the helically-grooved nut, all as will behereinafter more fully described.

The watch-movement A, which is of the usual description, is providedwith a balancebridge B, to which is attached in the usual way theregulator-lever O. Under the free extremity of the regulator-lever O issup ported a curved screw D by the frame E, the center of the curvatureof the said screw being coincident with the center of motion of theregulator-lever 0. Upon the curved screw D is placed a nut F, providedat one end with a circumferential groove to for receiving the free endof the regulator-lever O. The remainder of the nut F is groovedhelically. Upon a screw I), inserted in the regulatorlever O, isjournaled a star-wheel G, which may be turned by a needle or anyconvenient instrument. A series of pins 0 project from the under surfaceof the star-wheel G, and are arranged to enter the helical grooves ofthe nut F when the star-wheel G is turned. In this manner by turning thestar-wheel G the pins 0 by entering the grooves of the nut F cause thenut to rotate upon the curved screw D and carry the regulator-lever O inone direction or the other, according to the direction of the rotationof the star-wheel G.

The frame E is provided with a scale (Z for indicating the amount ofmotion of the regulator-lever C.

By means of my improved regulating device any owner of a watch mayreadily regulate it without the necessity of taking it to a watch-maker.

Having thus described my invention, I claim as new and desire to securebyLetters Patent 1. The combination, with the regulator-lever O, of thecurved screw D, the circumferentially and helically grooved nut F, and.the star-wheel G, provided with the pins 0, substantially as specified.

2. The combination, with the regulator-lever O, of the curved screw D,the circumferentially and helically grooved nut F, the starwheel G,provided with the pins 0, and the frame E, provided with the scale (I,substantially as specified. Y
